Entergy's Eternal Power Struggle: MISO Move Decades in the Making

by Luke Jones  on Monday, Nov. 26, 2012 12:00 am  

Years of controversy and litigation have led to Entergy Corp. joining a regional transmission operator, which manages Entergy’s power lines, and selling the lines themselves to a third party, ITC Holdings Corp. 

As far as benefits to ratepayers, Entergy Arkansas expects to save about $250 million over a period of 10 years due to the MISO move.

On day one, McDonald said, the ITC and MISO deals won’t significantly change bills. Over a longer period, however, the MISO benefits, as well as the end of the FERC-imposed payments, should lower costs, he said. Those payments will end in January 2014.

“Entergy operating companies will be realizing the savings through the wholesale markets,” Hillman said. “In a wholesale, nondiscriminatory type of market, those savings are passed onto ratepayers.”

And the name on the energy bill for Entergy’s current customers in Arkansas?

“We’ll still be Entergy Arkansas,” McDonald said. “We’ll still be a subsidiary of our parent company, Entergy Corp. We’ll just be operating under a different agreement.”
